Explicație pas cu pas:
a)
a + c = 135
b = 27
a + b + c = a + c + b = 135 + 27 = 162
b)
a + c = 53
a + 27 + c = a + c + 27 = 53 + 27 = 80
c)
a + b + c = 132
b = 75
a + c = 132 - b = 132 - 75 = 57
d)
a = 132
b + c = 75
a - b - c = a - (b + c) = 132 - 75 = 57
e)
a - b - c = 73
a = 79
a - (b + c) = 73
79 - (b + c) = 73
b + c = 79 - 73 = 6
f)
a - b = 27
c = 53
a - (b - c) = a - b + c = 27 + 53 = 80
g)
a - c = 29
b = 11
a + (b - c) = a + b - c = a - c + b = 29 + 11 = 40
